7.0 Features
7.1 Miter Cutting Head
The miter cutting head is the unit that cuts the
material and consists of a cast iron base, blade
support unit and guard, transmission unit, and
motor. The depth of cut is set by adjusting the
depth cut stop. The miter cutting head swivels
and locks into -45º, 90º, and +45º by means of a
locking mechanism. Depressing the mechanism
overrides the lock, permitting the head to adjust
to any position between -45º and +45.
7.2 Miter Position Lock
The miter position lock secures the miter cutting
head from movement. The miter is secured
when the lock is pushed all the way to the left
and can be positioned when the lock is moved to
the right.
7.3 Self-centering Vise
The self-centering vise holds the work piece in
place during cutting. The work piece is secured
in the vise by turning the vise handles.
7.4 Blade Lock
The blade lock secures the arbor from rotation
when attempting to change blades. The blade
lock is pushed in when changing blades.
The blade lock is not spring
loaded and must be pulled out after the blade
has been replaced and before operating the
machine.
7.5 Controls
The control panel consists of the Power (On/Off)
switch and High/Stop/Low switch, and an
integral coolant system. To operate the
machine, the Power switch must be set to On
and the High/Stop/Low switch must be set for Hi
or Low. Then depress the trigger handle to start.
7.6 Trigger Handle
The trigger handle (Figure 1) is located on the
operating lever used to raise and lower the saw.
It contains a micro-switch, which is activated
when the operator depresses the run trigger.

7.7 Mist Coolant System
The mist coolant system sprays a coolant mist
onto the saw blade during the cutting operation,
cooling it and the work piece being cut. Air is
supplied from a compressor to the air intake
valve (A) located near the bottom of the cabinet
on the left side. When the head is moved off of
the top limit switch (Figure 2) when beginning a
cut, the pneumatic switch (B) is activated,
allowing air to flow through the air tube (C) and
into the orifice (not shown), causing coolant to
be drawn through the coolant tube (D). The
pneumatic valve (E) adjusts the amount of
airflow. Air and coolant is mixed in the orifice
and sprayed onto the saw blade.
Use a water-soluble synthetic coolant with this
mist coolant system. The ratio should be
between 7:1 to 10:1. Coolant should be changed
regularly. Some recommended brands are DoAll
and Lenox. These coolants are available at your
local industrial distributor.
